Broken again, loosing faith

I'm guessing IndyIan's rock maybe a bit too heavy. Pretty easy to calculate a rough weight with dimensions.

The rock in that first pic you posted looks bigger to me, but they all look bigger than what I would have though you'd be able to lift. The L39 is holding a couple that surprise me too.

You guys are killing me, I'm going to have to bolt the zamboni back on, fillr up and give it one last shot. Might try a little later today or tomorrow, pictures to follow one way or another.

From the pics posted so far, I'd say you'd be able to pick up that rock if you tried with pallet forks or a grapple from the side instead of from the end. It's just too long and sticks out to far to use the bucket.

I guesstimated it weighed about the same as my tractor, and I could only lift the big end when part was counter balanced on a roller. And even that put a permanent little dip in the middle of the bucket. 6'x4'x1.5'x168lb/ft^3 is 6048lbs.
Here's another picture

On the rollers though it was an easy push and the HST was nice for just inching along.
Anyways, I wouldn't go too crazy with big rocks until you get some serious ballast back there. I kind of worry about the front axle loading with the whole a tractor plus whatever is in the bucket balanced on those bearings... Not that I've heard of a problem but just the same.

Think you could be right, most of the rock is a few feet in front of the bucket and so would the weight of it.

I have always wondered what would happen if the bucket was dramatically overloaded. Would it just not lift the load or could the cylinders be damaged?

Normally the relief valve goes into relief, and you quit yanking on the stick. End result nothing happens. Course without proper ballast on the rear, the tractor rear end goes in the air is another result. Try it sometime. If you have a rock ledge handy, or a really big rock or some other immovable object you can tie into. With apologies to Dirty Harry, Clint Eastwood " A man has got to know his limitations"

The hydraulics just go over the relief, do it all the time. I have alot of people wanting me to turn the reliefs up but they make a great safety valve so to speak. you go past the design limits and something WILL break sooner or later. CJ

Do you have your relief valve bumped up a bit? The specs on L39 and DKSE loaders seem to be identical. I guess the rocks look bigger when you pick them up!

I have the hydralics less than 100 Psi over factory which is about 2800 psi. When I got the machine it was set at 2200! It could balely lift 1500 - 1600 Lbs. Kubota rates the lift to center bucket, not the pins.

Those rock are the max the machine could lift. I placed them in the bucket with my excavator. There is no other way to fit that big a rock in the bucket and not have it fal out trying to lift. Yes the L39 would lift the rocks to about midpoint.

The L39 is not real strong in the curl and has the Grand L front axle. The new L45 has an M series design front axle and they bumped the curl cylinders up in diameter to where it will curl 4300 Lbs vs 3550 on the L39.

I've got about 1,000 lbs in wheel weights and other stuff bringing the weight to over 8000 lbs. Kubota for some reason likes small front tires on their comercial machines. Sinks real good in soft conditions. The L39 & L 45 should be fitted with 16 x 20 rears (43" dia. vs. 40) and 10 x 16.5 fronts (29 " diameter vs 27") The M59 should have 12.5 X 16.5 fronts.

The M59 is over 5000 Lbs on the curl. Great tractors but problem is those tractors cost close to what I think full size industrial hoe with low hours cost. Central Valley Tractor is a good Kioti dealer up here. I wish Kioti would come out with a TLB with a dedicated real strong hoe.

Loader specs eh! I wonder how Kioti measured the breakout force, it seems like they used the lift cylinders capacity? 3400lbs made sense with my rock as I could lift it up a little ways but the curl had no issues lifting either end up and down... So I think its significantly more using the curl even with the SSQA. I don't really want it any stronger anyways for my rookie skills atleast, its hard to get a feel for how much force it applies for tricky stuff like taking round bales of my trailer, or popping out a rock... I too have watched my front tires sink magically into the ground while waiting for a rock to move out of the ground.:confused2:

Well, if it ain't something, it's something else. I was going to give the rock one more try, but my water pump wouldn't go. I've never had to pull it more than twice to start it, but I forgot it out in the rain a couple days ago and I think the gas took in some water. Anyway, I'll try and get it working this afternoon and go for the rock tomorrow morning. Here's a couple pics of my Zamboni set up.

Well, I drained and changed the gas and still nothing. Fiddled with the switch (on/off) and off it went. So with the tanks full of water, I headed back down the road to try one last time. The rock is down off the side of the road so I put it in 4 wheel drive, low range. I can get under the rock no problem with the forks but, still no lift. I tried backing a little which started bringing the front wheels up to the road level, but also started raising the FEL. I very quickly ended up in a familiar position, with both rear (loaded) wheels, my box blade and two full barrels of water high and dry hanging in the air. The rock wins this one, I picked up a smaller one and headed home. Here's some pictures of the imovable rock plus a couple of the rock I took. My cell phone is in one pic for reference. Still can't find the camera, took the kids again :laughing:
